Enable Unobtrusive Validation in ASP.NET Application

How to Enable Unobtrusive Validation in ASP.NET Application.

Prior to Unobtrusive Validation feature, a lot of JavaScript would get added into a page for each of the different validator controls.

• Add JQuery Reference in to Application.
• Create New ASP.net Web Application
• Right Click Reference and click on Manage NuGet package

• Install JQuery Reference

There are three way to enabled Unobtrusive Validation into asp.net application

Add App key in Web.Config File as:

 <appsettings>

      <add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms">

      </add>

    </appsettings>

We can also set it at Application_Start method in Global.asax file  as

Add Referance: using System.Web.UI;
Add Following Code in Application Start Event

 void Application_Start(object sender, EventArgs e)

        {

            ValidationSettings.UnobtrusiveValidationMode = UnobtrusiveValidationMode.None;

        }

We can also set it at page level by setting the property of Page class as

protected void Page_Load(object sender, EventArgs e)

        {

             //Code UnobtrusiveValidationMode at Page Level

            Page.UnobtrusiveValidationMode = System.Web.UI.UnobtrusiveValidationMode.WebForms; 

        }

Unobtrusive Validation Benefit:

• It can minimize the size of your overall page
• It involves less JavaScript overall on page
